CANDLE-MACHINE.

Speeifica'tionof; Letters Patent. I Pate ted NO 1914 Application an .April 10,1913. Serial 1T0; 'zqqgga To-aZZ whom it may concern 'Be it known that we,;lVILLIAivIf HARPER DAY and VVILLIAMl EURGH, subjects of the King of Great :Britain, residing at The Novelty lvorkallounslow, in the county of Middlesex, England, have invented new and useful Improvements in and Relating to Candle-ll lachinesof which the following is a specification.

Our invention relatesto improvements in candle machines. a v v Candles are now usually molded in machines inwhioh thereare a .series of vertical molds and beneath said molds a vertically movable ejector plate on which are loosely mounted by means of lock nuts a series of pistons or ejectors corresponding in nums her with and registering with the molds 'of the mach ne. 1

The method hitherto employed of loosely fastening the ejectors onto the ejeetorplate by means of lock nuts has the disadvantage in practice that there is a: tendency for said retaining nuts to, creep on the ejectorsdun ing the operation of the machine With the result that in course of timexthe e ect-017s on the plate vary in height and consequently chines of large capacity.

the candles cast in the maohine are not of the same length. Further it is ,quite impossible togremove an ejector fromthe inner. portions of theplate should such ejector be bent without first removing a number of theejectors in front. .Theoperationzof erecting and adjusting th e c'height of the ejectors ,on tllell plate is found to occupy a very considerable amount of'tlme 1n1ma .Our invention is designed to i provide improvedmeans whereby the ejectors are loosely mounted on the ejector plate in such a manner that any oneof theseries of ejectors can; be removedv at once from the reason and 45.

plate should it be bent or for any-other a new ejector dropped into p0- sition.

The improved ejector plate of our inventionallows of a considerable increase in the oapacityof the machineand the consequent a more positive controlling mechanism in the lifting gear than that obtained 'from the pawlcatoh hitherto used.

. Our invention is illustrated by example in the accompanying drawings, in which r Figure 1 shows an isometric viewof our way of 9 improved candle machine. Fig. 2 shows a side view of the e ector plate. Fig.- 3 shows a plan'view partly broken away of the ejector plate SllOWlllIl Fig. 2. Figs. et and 5 show detail plan and sectionalviews of the and lowering the ejectorplate. Fig. 8 shows a plan view of the mechanism shown in Fig. 7. v controller and Fig. 10 sho'wsadetail view of the brake member.

by means of steel trusses 17 shown in Figs. 2, 3 and 6. The upper surface ofsaid e ecsliding plates 18 provided with a series of circular openings 19 corresponding with and registering in'one position on said plate18: with :the verticalmolds v(not shownj).- Ive arrange as extensions to; said circular open-- ings 19 in said sliding. plate 18 a series of Fig. 9 shows a detail view of the .dieferi'ing now, to the drawings :The ,2 ejector plate 2 is prevented from buckling angularzslots 21 being adapted to be moved into a position: in register when said openings 19 are moved. out of register with said molds a ,1 I --The lower extremities of the ejectorsl't are threaded and provided with means for varying their efiective length comprisingaseries Y i of adjustable collars 22 as shown in Figs. 4

and 5 of smaller diameter 'thai1.tl1e diameter the vertical cylindrical molds (not shown) ith the molds i of the circular openings 19 cut in said slid 1 'ingupper plate 1 8. 'In use the said sliding plate 18 is first moved to the positionin which the circularoopenings 19' register With and the eje'ctors': 14 are then dropped from 3 thetop of the machine into position on the ejector plate 2 through the molds, their lower collared ends passing through I the openings 19 in the upper sliding plate 18.

The upper sliding plate is then moved across the ejector plate 2 on which it is'mounted thus moving the circular openings 19 out of register with the molds and retaining the ejectors 1n position in the slotted extensions of said openings 19.

Convenient locking means are provided forholdingthe; sliding plate 18in one or other of its two positions such as the ing bolts 23 shown in Figs. 3 and 6. q

- It W111 be. obviousthat with as. ads 1 75 tor plate 2 h as mounted thereon one or more I described arrangement ejector orfseries of e ectors 1% in the machine can be 1nstantaneous'ly unlocked and removed from the ejector plate 2 and replaced without disturbing the other ejectors.

In order that the downward movement of the ejector plate and consequently the length of the candles can be adjusted, we provide an adjustable stop 24- forming the upper extremity of the screwed spindle mounted in thelugs 26 and adapted to moveup or down by the handle 27. The lug 28 on the yoke 3 is adapted to engage the upper extremity of the stop 24 and consequently according to the position of the ejectors in the candle molds, the length of the candles, is adjusted.

We provide controlling mechanism shown in Figs. 7 to 10 whereby the rack 1 and consequently the-ejector plate 2 which is connected with said rack through the yoke 3 as shown in Fig. 1, can be raised or l0wered to any desired position and held there when pressure is taken off the operating handle 4. The yoke 3 is provided with angular extremities 5.projecting inward through the guiding slots '6 of the machine; the ejector. plate 2'resting on said extremities 5 and being held in .position thereon by the lugs 7 shown in Fig. 2. v

The controller ofour invention comprises a cam shaped lifting member 8 combined with an angular engaging member 9 said members being mounted on the spindle 10 of the handle t in. the position hitherto occupied by the ratchet wheel. A pinion 34 is mounted on said spindle 10 behind the'an- I gular engaging member 9. "This pinion is in engagement with the gear wheelt35 which is mounted on the same shaft and adapted to rotate with the pinion 36 in engagement with said rack 1. In combination with said controller we arrange a saddle 11' depressed by the adjustable springs 12 provided with a curved surface adapted to engage the cam member 8 and a fiat surface'13 adapted to engage the angular member 9.

In use the operator turns the handle 4 thus turning the controller 8 which lifts the saddle 11 against the pressure of its springs 12 and allows the angular member 9 to pass theflat' surface 13 of said saddle and the I spindle 10 to be turned and consequently the ejector plate 2 to be raised or lowered through the rack 1 and the yoke 3 attached at the lower extremity ofsaid rack. When however, pressure is taken off the handle '4 the curved surface of said saddle ll immediatelydrops into engagement with an 'in wardly curved surface on the controller,

I while a fiat surface of the angular engaging member 9 comes into engagement with a flat surface 13 ofsaid saddle, thus firmly holding the ejector plate 2 and consequently the ejectors 14 carried by said plate in the or other of, their two positions.

position towhich they have been raised or lowered. It is now usual to carry the spindle 10 operated by the handle t throughout the length of the machine and to arrange a pinion wheel adapted to engage a rack attached to the ejector plate at the other end of said machine, thus assuring that the ejector plate is raised at both endssimultaneously; lVe prefer to extend the said spindle 1O beyond the end of said machine andto mount thereon a brake disk 15 as shown in Fig. 10 of convenient diameter adapted to be engaged by the spring controlled saddle 16. Any convenient means may be provided for adjusting the tension on the springs engaging said saddle l6 and consequently the friction of said brake disk 15. I

. It will be readily understood that with the above described mechanism it is impossible to inadvertently allow the e ector plate 2 to fall to the bottom of the machine.

What we claim is V 1. In a candle making machine, the combination with a series of vertical 1nolds,'a series of ejectors cooperating therewith, means for adjusting the effective length of said ejectors, a vertically movable ejector plate supporting said ejectors, and a transit versely movable locking member adapted to lock the ejectors upon said plate.
